Thermostatic Radiator Valve Head Won't Fit

[jojo77]

I have an older house and one of the rad valves has just broken off, and I think the rest will soon do the same as they're all the same age.
The issue is that the trv I bought in a plumbers shop doesn't fit. The finger bits (technical description;-/) don't fit over the thread on the radiator to grip it.

I saw a previous post https://www.diynot.com/diy/threads/thermostatic-radiator-valve-head-wont-fit.461595/
where you recommended a head based on their photos, I've attached some.
Can you please recommend a solution for these rads.

thanks
