A mechanical feedback control device for a redundant hydraulic actuator having two hydraulic cylinders operated by respective hydraulic valves and interposed between a fixed connection and a movable connection of the actuator; the device having an input lever connected to two feedback rods connected to the movable connection of the actuator, and a transmission lever which, when moved by the input lever, rotates a pin to activate two shafts controlling respective slides of the valves. The input lever, the transmission lever and the pin form a closed-loop structure for transmitting displacement to each of the shafts, so that each of the slides can be moved via two different kinematic chains.
