Patent ID: 8403054

Claim:
A valve for use in a subsea assembly comprising: a valve member that is stroked between open and closed positions by a rotatable shaft that comprises a drive shaft and a driven shaft having a driven member; and a torque limiting device operably associated with the shaft comprising: an annular collar and a slot formed through a sidewall of the annular collar having an outer edge that is oblique to an axis of the collar, so that when the torque limiting device is in a locked position the driven member engages the outer edge, and rotation of the driven shaft causes rotation of the drive shaft to stroke the valve member, and so that when the driven member slides along the outer edge in a direction that approaches an end of the collar having a profile, the collar disengages from the drive shaft with the profile disengaged from the shaft that releases the valve member from movement with the shaft when a selected torque on the shaft is reached, and the torque limiting device being resettable from the released position to the locked position.
