Broken eccentric shaft actuator ( in engine )

Someone did the valve cover gaskets and was having issues after . Long story short , I Decided to just go back over their work and Redo it as their was still a leak and the car wasn't not starting and having different issues .
I go to unscrew this and the passenger came right out , So I decided to check the driver and same thing almost in the same spot . Not sure if they broke it or it locked up after they fixed or maybe the over tightened it or what ( no clue )
Anyways what can be done if anything ?
I took pictures of how it looks and how it should look ..
The bottom piece looks like it's stuck in the engine .

Looks like perhaps that when the valve cover was done the valvetronic motors were not calibrated and they may have snapped.

So I got one out . Just posting for others if they run into the same issue .
The valve gasket was leaking anyway so I had to take it off the cover anyway . Once I did I took tweezers and unscrewed it counter clockwise until it came up enough to pop it out up top . I'm assuming this could of been done through the top , without removing the cover if you tried .
I attached some pictures . If anyone has questions feel free to ask .

This would be pretty hard to do, as they just screw down into place. Maybe someone tried forcing them down, instead of screwing them down? Either way this was a stupid & expensive mistake! The motors calibrate themselves by turning the key on without cranking the motor. You will here them turn back & forth while they are calibrating if you listen.
