An ultrasonic surgical instrument is provided and includes a housing. A shaft is supported on the housing and defines a longitudinal axis therethrough. The shaft supports a jaw member at a distal end thereof. The jaw member is movable between open and clamping configurations. A probe includes proximal and distal ends. The distal end has an active blade thereon configured to effect tissue when the jaw member is in the clamping configuration. The proximal end has at least one mating feature thereon. A rotating assembly operably supported on the housing is configured to rotate the shaft. The rotating assembly includes a torque adapter that is engageable with the at least one mating feature to selectively and releasably couple the probe to the housing.
