A rod ring is fixed to one side of the drive gear. A flank gear having a plurality of flank gear clearance holes corresponding to the drive gear clearance holes is also mounted on the drive shaft adjacent to the drive gear. A force ring having a plurality of receiving holes is mounted to the flank gear. Springs having a first end fixed to the rod ring and extend through the drive gear clearance holes, the flank gear clearance holes, and into the receiving holes. The springs exert a force biasing the flank gear and the drive gear to rotate in opposite directions.
