I'm curious if this is down to cost, stupidity or some technical issue with the linear actuators. It seems you could get the electronics, 2 or even 4 AAA batteries ( in the corners) and a linear actuator in far less space.

Most TRV valve heads do need quite alot of force, more importantly you
need to be able to turn the motor off, and not have the valve drift back
