Abstract
A rotary actuator for a valve is associated with an indicator mechanism provided entirely exteriorily to the housing of the valve and out of axial alignment with the valve spindle. The indicator rotates with an actuating member of the valve and is movable relative to a surface of the actuating member to provide a visual and tactile indication of the operative position of the valve.
