Claim 0:
1. A splined shaft for a turbine engine having a periphery and comprising splines evenly distributed over the periphery, the splines being spaced apart from each other, at least one portion of the splines being spaced apart by a modified pitch p with respect to a nominal pitch pn of the splines, a ratio of an absolute value of a difference between the modified pitch and the nominal pitch (Δp), to the nominal pitch, i.e. |pn−p|/pn being different from zero, wherein the difference (Δp) between the nominal pitch pn between the splines with respect to the modified pitch p, along the periphery, progressively increases or decreases from one spline to another, as the periphery of the splined shaft is covered, said difference increasing up to a maximum (Δpmax) before decreasing down to a minimum (Δpmin).
