how to remove this please

[thamesc180k]

hi all, has someone removed this control knob from their seat (drivers), if so how?
Seems to be on tight and dont wish to break it in trying. Cant find any info on the net either.
The motor to raise/lower the seat is jamming on the way down, blowing the fuse, so needs looking at.
Thanks

I think you find an Allen key type grub screw
