Default Cannot remove Zone Controller

Hi, I have a gas fired boiler for a hydronic heating system. I have 3 zones using Honeywell V8043F control valves. I recently replaced one which the guy servicing the boiler said had a short (it was sparking) and all is well with that zone.
When the guy was servicing the system he took off the powerheads and lubed the valve stems, all except one powerhead which would not come off. Has anyone experienced this?
I can take out the 2 screws which hold the powerhead onto the valve body and wiggle it from side to side but it will not come off. (usually these just lift off easily).
I have been very careful not to get too rough with it as i do not want to damage the valve and have to sweat a new one in place.
Any ideas?

Do you have the manual lever in the open position?

I've tried it in the open and closed position, (using the lever), the result is the same.
thanks

If I'm not mistaken there is a small clip that fastens the motor to the stem that has to be removed.

No clip, but i dismantled the power head and found the black plastic part was damaged, causing it to sit at an angle. Assume this was the problem.
Back in business with a new powerhead.
