Abstract
A method of forming a shaft for transferring force from a driving element to a driven element makes use of a tube. The tube is deformed to define distal ends of said shaft. At least one of the distal ends of the tube is trimmed to define a yoke for engaging one of the driving element or the driven element, with the yoke being integrally formed with the shaft.

- deforming a tube to define distal ends of said shaft, said tube having a wall thickness;
- folding a portion of at least one of said distal ends onto itself to establish a flange, said at least one of said distal ends having an increased thickness that is greater than said wall thickness;
- and
- trimming said at least one of said distal ends to define a yoke for engaging one of the driving element or the driven element, said yoke comprising a portion of said flange and being integrally formed with said shaft.
