A hand-wheel actuator for preventing over rotation of a hand-wheel shaft. The hand-wheel actuator comprises a housing that defines an opening aligned about an axis. The hand-wheel shaft extends along and is rotatable about the axis. A drive gear is rotationally coupled to the hand-wheel shaft, wherein the drive gear is at least partially disposed in the opening and includes a drive gear tooth. A stop gear is coupled to the housing and includes a plurality of stop gear teeth for engagement with the drive gear tooth and prevents rotation of the drive gear over a predetermined threshold.
