Coupler Valve enables simple hose attachment to an irrigation supply line underground. They are often found underneath a valve box and are connected to temporary irrigation sprinklers or hand-watering locations. Basically, it is a mechanical component that joins two shafts together in order to precisely transmit power from the drive side to the driven side while compensating for mounting error (misalignment), etc. of the two shafts.
