Abstract: Embodiments of the present disclosure provide a control system including: a power wrench; and a controller operatively connected to the power wrench, wherein the controller is configured to perform actions including: directing an operative head of the power wrench to turn in response to a pressure-angle derivative of the operative head being below a predetermined threshold, defining an origin at an angular position of the operative head where the pressure-angle derivative of the operative head exceeds the predetermined threshold, directing the operative head to turn by an angular step in response to: the pressure-angle derivative of the operative head exceeding the predetermined threshold, and an angular differential of the operative head being less than a target value; and directing the operative head to cease turning in response to the angular differential of the operative head being approximately equal to or greater than the target value.

Abstract: Shaft assemblies, turbomachines, and methods of servicing a turbomachine are provided. A shaft assembly includes a first shaft having a first rabbet annularly defined therein. The first rabbet includes a first axially extending face and a first radially extending face. A second shaft coupled to the first shaft. The second shaft includes a second rabbet annularly defined therein and positioned opposite the first rabbet. The second rabbet includes a second axially extending face and a second radially extending face. A patch ring is mounted between the first rabbet and the second rabbet. The patch ring includes a main body positioned between and in contact with the first axially extending face and the second axially extending face. A first arm extends radially outward from the main body, and a second arm extends radially inward from the main body.
