Correct. You have to press the 'notch' at the back in and turn the adapter anti - clockwise. Doing that, but it just keeps turning.

Correct, but when it screwed in, it makes a clicking sound. Something locks it in place. Just can't unscrew it.

The 'underside' is in a bit of a state, pump pliers etc (very embarrassing).

This video shows the adapter and base of TRV after 9.01 minutes -

But that is a video of what Andy Brown says, it doesn't show what your problem / difficulty is.

The video shows more then a picture of the 'underside' of the adapter would. It shows the 'underside' of the TRV and the 'top and underside' of the adapter. There is something that locks it in place.
So that's only reason for posting the video. I know the TRV is 100% faulty, but I need to remove the M30 adapter. Others has encountered the same problem. There seems to be an 'inherent' design fault.

It sounds to me as though you have butchered it somehow...?

And as Richard said an prom you tube video doesn't show what you have done to your valve anymore than my adding a link to all the negative reviews of these valves on Screwfix... https://www.screwfix.com/p/hive-smart-trv-head-white/265GX?

A photo of the actual bit you are struggling with could be of help top someone familiar with these TRV heads..

(from several reviews they don't look the most reliable bit of kit?)

Butchered is an understatement (there are reasons). These TRV's are identical to the Danfoss Eco's TRV's.
