1. A torque transfer assembly comprising:
a drive shaft;
a driven shaft;
wherein the drive shaft comprises:
a motor shaft configured to be connected to and rotated by a motor; and
a cam shaft connected to and rotatable with the motor shaft;
wherein the driven shaft is connected to and rotatable with the cam shaft; and
wherein the cam shaft is formed of a dielectric material defining an insulating barrier between the drive and the driven shaft; and
a bushing connected to the cam shaft and via which the cam shaft is connected to the motor shaft;
wherein the cam shaft is provided with a protrusion from a first side to engage in a matching recess in the driven shaft, and a recess on an opposite, second side to receive the bushing in form fitting engagement;
wherein the bushing is provided with a bore extending axially therethrough to receive the motor shaft in such a manner as to ensure rotation of the bushing with rotation of the motor shaft;
wherein the bushing also includes a bore extending radially through the bushing, the motor shaft having a corresponding bore therethrough, such that when the bore through the bushing and the bore through the motor shaft are aligned, a shear pin bore is formed to receive a shear pin therethrough.
