Control device for an aircraft roll or pitch control surface (116). The device comprises at least two actuators (110, 112, 114), each with at least one electrical control input (111a, 113a, 115a). At least one of the actuators (115), called the hybrid actuator, also has a mechanical control input (115b). An electrical control system for the actuators may be in a "normal flight" state in which at least one of the actuators actuates the control surface (116), or a "maneuver" state in which at least two actuators actuate the control surface, or an "electrical control failure" state in which the hybrid actuator (115) actuates the control surface controlled from the mechanical control input.
