# Quick release disconnect coupling device for drive shaft segments

## Abstract

A coupling device for transmitting torque between two rotating drive shaft segments. The coupling device includes a locking mechanism for preventing axial excursions of the drive shaft segments relative to one another when the drive shaft segments are coupled and transmitting torque. The coupling device, furthermore, provides a means for quick disconnect of the drive shaft segments when the transmission of torque is no longer desired and decoupling is preferred. The coupling device, additionally, includes a guide pin and sleeve arrangement for piloting the drive shaft segments during coupling. A drive system is also provided which includes a flexible coupling for accommodating axial and angular misalignment of the drive shaft segments relative to one another.
