Abstract
An actuator system for use in selectively engaging an input to an output. The actuator system includes an input sub-system having an input component configured to connect to an input element which is in turn connected to a work source. The actuator system also includes an output sub-system being connectable to the input sub-system for receiving work from the work source via the input sub-system. The actuator system further includes an actuator sub-system having an active material and an actuating component. The actuator sub-system is configured so that the active material, when activated, causes the actuating component to move from a first state to a second state to disengage the input and output sub-systems.
