A torque tool for tightening or loosening connections has a driving element engageable with a turnable part of the connection for turning the turnable part of the connection for tightening or loosening the connection and turnable about an axis, and a power drive configured for acting on the driving element such that the drive acts on the driving element to turn the driving element and thereby to turn the turnable part of the connection over a partial stroke and a space is formed between the drive and the driving element, and the drive is then displaced over the space toward the driving element to act again on the driving element to turn the driving element and thereby to further turn the turnable part of the connection over a further partial stroke.
