Abstract
The present invention provides a quick disconnect coupling for a work tool to a machine. The invention in its preferred embodiment provides a coupling having fluid and electrical connections and also providing alignment independent of the locking mechanism. The present invention also is advantageous in that the locking mechanism is protected from the environment when the coupling halves are not mated and also prevents a false lock-up unless the halves of the coupling are mated and aligned.
