Abstract
A well tool with a housing has an actuator sleeve in the housing. The actuator sleeve has an internal shifting tool engaging profile. An actuator is in the housing. The actuator is responsive to a remote signal to move the actuator sleeve from a first position to a second position. A dog is in the housing, supported to couple the actuator sleeve to the actuator when the actuator sleeve is in the first position and unsupported to allow the actuator sleeve to uncouple from the actuator when the actuator sleeve is in the second position.
