Claim Text:
1. A torsional frequency adjustor for a rotating body, the torsional frequency adjuster comprising: a first ring having a first engagement surface parallel to an outer surface of the rotating body, the first engagement surface having a total arcuate length that is smaller than a circumference of the outer surface of the rotating body, the first ring further having a first wedge surface inclined at a first angle with respect to the first engagement surface; a second ring having a second wedge surface corresponding to and selectively engaging the first wedge surface, a total arcuate length of the second wedge surface being smaller than a total arcuate length of the first wedge surface at each corresponding point along a shared longitudinal axis of the first and second rings; an inducer that, in operation, draws the first wedge surface into engagement with a portion of the second wedge surface, thereby inducing an interference fit of the first engagement surface with the outer surface of the rotating body, wherein at least one of the first ring or the second ring includes a plurality of arcuate segments and at least one gap between an adjacent pair of the plurality of arcuate segments.
