An actuator includes a drive body including a torque-transfer surface configured to receive a torque. The actuator further includes: a drivable body including an output shaft such that rotation of the drive body causes movement of the output shaft; a first bearing configured to transfer thrust forces from the output shaft in a first direction; and a second bearing configured to transfer thrust forces from the output shaft in a second direction. At least the first bearing extends in a radial dimension beyond the torque-transfer surface.
