That which is claimed is: 1. A coupling device for a fire hose, comprising: coupling means for creating a seal at an adapter connection point; and pressure relieving means for relieving trapped pressure at an adapter connection point, wherein the coupling means comprises a first fitting having thre
That which is claimed is: 1. A coupling device for a fire hose, comprising: coupling means for creating a seal at an adapter connection point; and pressure relieving means for relieving trapped pressure at an adapter connection point, wherein the coupling means comprises a first fitting having threads and a second fitting having threads, and wherein the pressure relieving means comprises at least one channel in at least one of the threads of the first fitting and the threads of the second fitting for directing the trapped pressure away from a user when the seal is disengaged while the coupling means is engaged. 2. The coupling device of claim 1, wherein the pressure relieving means provides a visual indication of any pressure present in the fire hose when the seal is disengaged. 3. A coupling device for an adapter connection point, comprising: a first fitting, the first fitting comprises a male fitting having threads, a second fitting, the second fitting comprises a female fitting having threads, wherein the first fitting and the second fitting are capable of forming a seal when completely engaged, wherein at least one of the first fitting and the second fitting comprise at least one channel comprising a leak path for relieving pressure at the adapter connection point, and wherein the at least one channel is in at least one of the threads of the first fitting and the threads of the second fitting and is capable of relieving pressure when the seal is disengaged before the first fitting and the second fitting are disengaged. 4. A coupling device for an adapter connection point, comprising: a first fitting, the first fitting comprises a male fitting having threads, and a second fitting, the second fitting comprises a female fitting having threads, wherein the first fitting and the second fitting are capable of being engaged with one another and forming a seal when completely engaged, wherein at least one of the first the second fitting comprises at least one channel in the threads wherein when the seal is disengaged any pressure at the adapter connection point is relieved through the at least one channel before the first fitting and the second fitting are disengaged from one another, and wherein the first fitting and second fitting are backwards compatible. 5. A coupling device for an adapter connection point, comprising: a first fitting; and a second fitting, wherein at least one of the first and the second fittings comprises at least one channel; wherein when a user begins to disengage the first and second fittings any trapped pressure will be relieved through the at least one channel prior to total disengagement of the first and second fittings; wherein the first and second fittings are threaded; wherein the first fitting is male; wherein the second fitting is female; and wherein the at least one channel comprises at least one channel through the wall of at least one of the fittings, beginning at a point on the interior of the fitting, the at least one channel being covered by the other fitting when the first and second fittings are completely engaged. 6. A pressure relieving safety device for an adapter connection point, comprising: a male fitting having threads, and a female fitting having threads, wherein at least one of the male fitting and the female fitting comprise at least one channel; the at least one channel comprises at least one interruption in the threads of at least one of the fittings, wherein the at least one channel is sealed when the male fitting and the female fitting are completely engaged, and wherein the at least one channel relieves pressure at the adapter connection point when the male fitting and the female fitting are engaged. 7. A coupling device for an adapter connection point, comprising, a male fitting having threads, a female fitting having threads, and at least one channel in at least one of the threads of the male fitting or the female fitting, wherein the male fitting is configured to form a seal when completely engaged with the female fitting, the seal prevents escape of liquid and gas from the adapter connection point through the at least one channel, and wherein the at least one channel is configured for liquid and gas to escape when the male fitting is engaged with the female fitting. 8. The coupling device of claim 7, wherein the at least one channel comprises at least one interruption in the threads of the male fitting. 9. The coupling device of claim 7, wherein the at least one channel comprises at least one interruption in the threads of the female fitting. 10. The coupling device of claim 7, wherein at least one channel comprises at least one interruption in the threads of the male fitting and at least one in the threads of the female fitting. 11. The coupling device of claim 10, wherein the interruptions comprise an axial interruption or a diagonal interruption. 12. The coupling device of claim 7, wherein the at least one channel comprises a tunnel through a wall of at least one of the male fitting or the female fitting.
