After the valve stem shaft rotates, the actuator feedback rod will disengage

Reason: Feedback that the fastening screw is loose. There may be vibration at the site.

When the valve operates, whether it is the actuator or the valve core, there is more or less a torque of rotation, which causes the valve stem to rotate to some extent
