No clutch but a couple of possibilities. It is possible but I don't think as likely in a 56 that strain during the reversal caused the snap ring holding the worm screw bearing to jump out of place. The worm is driven and connected to the armature via a pin thru the armature shaft which fit in slots in a sleeve which is part of the worm gear. If the ring came loose and bearing moved allowing the worm to shift it is possible the pins slipped out of the slots and armature is disconnected from the worm. This issue is detailed in bulletin 55T-12.
Another possibility is when the bars reversed, during the reversal process the bars ran into the case and with the lever prevented from moving, the huge amount of torque developed in the compensator caused the splines connecting the V shaped lever driving the bars to shear off. If there is any sign of bent bars that is the more likely scenario and the compensator needs to be removed and taken apart so the lever can be checked.
Here is what the lever from one compensator with that issue looked like.
