Does an adapter exist ….a M42 or M39 adapter where the register can be adjusted a few mm to achieve exact infinity focus?
It would be an adapter with built-in helicoid or another way to "parallel adjust"?

Why not.?   It is just a matter you can focus over your inifity point. It is not a hard fix at infinity. The important thing is, you can obtain infinity.

Better than a fixed adapter anyway is a M42 focusing helicoid such as this. Then get the M42 to Nikon Z adapter ring and Bob's your uncle. This will allow for continuous close focusing to macro distances

Maybe slightly off topic, but I have a Russian lens which I think is a Helios - anyway it is a 135mm f/3.5 preset which came with an M42 mount.  This can be easily detached and a Russian made Nikon F mount specific to the lens can then be attached in its place - which is what I did with this lens.  It works fine.

I believe that there are other Helios lenses that allow one to change the mount from M42 to Nikon F in this manner - it might pay to investigate if this option applies to your lens.

I found a similar M42 to M42 helicoid adapter which I have ordered. I have rings from 39 - 42   …...then I only need a Z-body.....but good to be prepared.

It will not work with a shorter focal length lens because the mirror will hit the rear element.

It sounds like a Jupiter 37A.

Yes thanks for this - I have just checked some images on the Internet and it is definitely a Jupiter 37A.  I am jailed up in quarantine in NZ due to NZ's COVID-19 lockdown, so cannot check the lens itself.

It sounds like a Jupiter 37A.

Any lens with M42 or M/L39 mount can easily be used on all Z cameras. There are loads of cheap adapters out there. In these dire times perhaps look for a supplier in Europe with the item(s) in stock instead of waiting for deliveries from China.

Why do you want to buy the heavy and sub par Helios 44 58mm f2 when you can get the original Zeiss Biotar 58mm f2 for USD200 ish.

At least get the Helios 40 85/1.5 which is a much better lens than the 44.

A good copy of Helios 44M (latest model) costs 40-50€ here in France. My sample like new gives good results from 2,8 and very good from 4-5,6. Biotar may be better but costs much more and you must be lucky to findd a like new sample !
My experience with the 1,5/85 Cyclop (same optics than Helios 40 but without aperture control) was not so good: heavy, fast aperture but not very easy to use nor very good wide open...
Here two examples (of my 2/58 Helios 44M) with Fuji XE2 ("velvia" rendition):
