Summary:A device for use in a subterranean well. The device comprising an actuator sleeve (210) coupled to an actuated element (200) of the device to operate the actuated element when the actuator shifts axially in the device, and an actuator (220) comprising a spring (222) to act on the actuator sleeve (210). The actuator is responsive, independent of well annulus pressure, to a remotely generated hydraulic signal in a central bore (208) of the device to change from an unactuated state, with the spring compressed, to an actuated state, with the spring expanded to shift the actuator sleeve from a first position to a second position, and the actuator is responsive to reset to the unactuated state when the spring is recompressed.
