As the title says, a Revotec adjustable fan controller M22 thread. MNore details are availble here: REVOTEC - M22 FAN CONTROLLER - EFC-M22
The unit was installed into my radiator, but has never been connected electrically or had coolant run past it.
It comes with the instructions and the unit itself, a few bits a missing (cable ties, the cap that goes over the the switch).
Asking for £25 + postage (the units sell for just under £70+p&P from Merlin )
