摘要： A method and system for coupling a drive unit to a tool adapter includes joining a first plate to a second plate; stabbing a stabbing member of the first plate into a hollow of the second plate; and rotating a bar of the second plate from an open position to a closed position to secure the stabbing member in the hollow. An embodiment includes positioning the tool adapter below the drive unit; stabbing a coupling head into a coupling recess; moving a fixation ring vertically; and securing bolts of the drive unit in notches of the coupling head.
