Abstract
An alignment sub may include a first sub body part rotatably coupled to a second sub body part. The first sub body part and second sub body part may be respectively non-rotatably coupled to a first wellbore tool and a second wellbore tool. A lock screw switchable between an unlocked state and a locked state may fix an angular position of the first sub body part relative to an angular position of the second sub body part when the lock screw is in the locked state.
