ABSTRACT:
A cylindrically shaped spacer between a shaft and hub of a turbine rotor of a gas turbine engine as fabricated from a flexible resilient material and interference fitted at discrete points on either side of the transverse axis of the spacer between the shaft and spacer and between the hub and spacer to impart a twist of the spacer about this axis to remain in contact with the hub and shaft throughout its entire rotating envelope.
