Abstract

A vane arm (22) includes a first end (70) and a second end (72); a shank (74) extending between the first end and the second end and having a first face (78) and a second face (76); a first hole (110) in the shank proximate the first end; a second hole (114) in the shank proximate the second end; and a transverse groove (80) in the first face intersecting the second hole. The transverse groove includes a base (83); a first open end (81) and a second open end (82); and a first side face (84) and a second side face (85). An asymmetry between the transverse groove first side face and second side face provides for uniquely angularly registering the vane arm to a shaft. At least one of the transverse groove first side face and second side face has a first facet (107) at a first angle of 0° to 20° over at least 20% of a depth (DG) of the transverse groove; and a second facet (104) at a second angle of 20° to 45° over at least 50% of the depth of the transverse groove. A vane assembly (20), a vane stage, as well as a method for using the vane arm are also provided.
