A coupling assembly includes a first coupling member having a pocket and a fluid passage that extends toward the pocket, and a second coupling member having a locking formation. The assembly further includes an engaging member that is received in the pocket and that is engageable with the locking formation. The fluid passage is configured to supply pressurized fluid toward the pocket to move the engaging member into contact with the locking formation to effect torque transfer between the coupling members.
