Claim:
1. A mechanical sensor coupled to an actuator, the mechanical sensor being operable to detect when the actuator is fully installed on a valve, the mechanical sensor comprising: an actuation disk configured for reciprocal, axial movement within a bore defined in a nose piece of the actuator; a location disk configured for reciprocal axial movement within the bore defined in the nose piece of the actuator; a sensor axially interposed between the actuation disk and location disk; wherein when the actuator is installed on a valve, a portion of the valve contacts the actuation disk and moves the actuation disk back against the sensor to indicate that the actuator is fully installed on the valve; and wherein the actuation disk and location disk are rotationally fixed relative to one another about a center longitudinal axis of the mechanical sensor by an anti-rotational arrangement.
