Floor heating adapter for Heimeier EMO T actuators

My floor heating ("U.S.H." brand) has a valve I've never seen anywhere before. It is an M30x1.5 thread. The Heimeier EMO T actuator would never touch the actual valve so I designed this extension part.
The slotted part fills the empty space in the valve for easy installation. For even easier installation you can heat up the actuator before screwing it on.

The part is designed for resin printing and can be printed directly on the buildplate without supports. Maybe it works with FDM too, but I didn't want to have thermoplastics where it's always warm and where there's a lot of pressure on the part (the valve spring is very strong!)

If anybody knows how this valve is called please let me know!
