This concept uses two small disks that are allowed to pivot. One disk is connected to the shaft, while the other is connected to a part between the distributor and shaft. A spring applies pressure to one of the disks, maintaining both disks at an angle. While at an angle the disks will be able to transmit power. When overloading occurs, the disk on the distributor side will stop. The other disk will want to keep turning and will therefore compress the spring and position the disks in a vertical configuration. Once in a vertical configuration the disk attached to the shaft will continue to turn.(The disk surfaces will be machined smooth to provide minimal friction.) The pivot points of the disks are offset to allow the system to only re-engage in one position after 360 degrees.
