An actuator swing arm mechanism includes extension shafts which are rigidly and coaxially attached to the drive shaft of an actuator at one end and rigidly attached to a swing arm at the other end. These extension shafts, rather than the drive shaft of the actuator itself, are rotatably supported by supporting members such that the weight of a heavy load on the swing arm is communicated through these extension shafts to and carried by these supporting members and the drive shaft of the actuator is relatively unaffected by the load.
