摘要： A rotating control device can include a rotatably mounted seal which sealingly engages a drill string, and a gripping device which grips the drill string and thereby forces the seal to rotate with the drill string. A drilling method can include positioning a drill string in a rotating control device, gripping the drill string with a gripping device of the rotating control device, and rotating the drill string, gripping engagement between the gripping device and the drill string causing a seal of the rotating control device to rotate along with the drill string. A well system can include a drill string, and a rotating control device including a seal which sealingly engages the drill string and a gripping device which grippingly engages the drill string.
