A device for transferring steering responsibility from a first electro-mechanical actuator to a second electro-mechanical actuator comprises a cylinder and a first piston slideably disposed within the cylinder. A second piston is slideably disposed within an interior chamber of the first piston. A first locking sleeve is disposed within the interior chamber, a second locking sleeve is disposed within the interior chamber in opposition to the first locking sleeve, a first spring is disposed within the interior chamber interposed between the first locking sleeve and the first piston, and a second spring is disposed within the interior chamber interposed between the second locking sleeve and the first piston. The pistons and the locking sleeves also each include at least one groove disposed therein. Snap rings may be disposed within the grooves. A damping mechanism may also be incorporated into the structure of the device. A method of transferring steering responsibility from a first electro-mechanical actuator to a second electro-mechanical actuator includes slideably disposing a first piston in an interior chamber of a cylinder, slideably disposing a second piston within the interior chamber of the first piston and allowing the first piston to move freely within the cylinder, allowing the second piston to move freely within the first piston, and allowing the first and second piston to be locked together.
