Abstract: An improved valve coupling method and apparatus is provided that resists the many forces associated with constant insertion and removal of access keys. The coupler apparatus is made of a non-corrosive metal alloy and includes a pair of specially formed integrated vertical wings which extend out in a tangential, as opposed to radial, direction from opposite sides of the coupler. Each of the wings is offset and includes at least one horizontal shelf portion. When buried in the soil, the vertical wings provide the coupler with frictional resistance to the screwing and unscrewing rotational forces imparted whenever a key is inserted or removed from the coupler, or from the movement of a hose attached to the key. Similarly, the horizontal shelf portions provide lateral support to resist the downward and upward forces associated with insertion and removal of a key, or contact with lawn maintenance equipment.
