A non-backdrivable clutched module for a bi-directional actuator such as actuators used for active aerodynamics on vehicles. The module has both a stopper mode and a clutch mode. During the stopper mode a back-driving force gets diverted away from the actuator using a locking bearing member. If the force is too great a clutch mode will disengage the back-driving force completely from the shaft connected to the actuator, thereby preventing damage to the actuator.
