A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a base and a patient support surface supported by the base. The patient support apparatus also comprises movable members that are movable between at least a first position and a second position. One or more hollow rotary actuators are coupled to each movable member. The hollow rotary actuator permits drive torque to move the movable member in a desired position between the first and second positions and restricts back drive torque from moving the movable member. The hollow rotary actuator is also hollow to allow objects to be placed therethrough.
