Abstract
A quick disconnect coupling including a first hub, a shaft fixedly connected to the first hub, the shaft being non-round in cross-section, and a second hub having a non-round recess extending therethrough, the non-round recess being sized to closely receive the shaft such that the second hub is capable of sliding along the shaft and is prevented from rotating about the shaft, wherein rotation of the first hub results in corresponding rotation of the second hub.
