a first set of bushings comprising a third set of bolt holes, wherein each bolt hole of the third set of bolt holes has a third bolt hole diameter, wherein the first set of bushings is disposed in the first set and second set of bushing receptacles in an installed configuration, wherein the installed configuration of the first set of bushings is configured to align the first and second rotational axes (36, 46) with one another; wherein in the uninstalled configuration the bushing diameter of the first set of bushings is greater than the bushing receptacle diameter of the first set and the second set of bushing receptacles, such that in the installed configuration the first set of bushings is interference fit in the first set and the second set of bushing receptacles; a set of bolts extending through the first, second, and third sets (34, 44, 54) of bolt holes to retain the first rotor component (16, 30), the second rotor component (16, 40), and the first set of bushings in the rotor assembly wherein the set of bolts has a bolt diameter that is less than the first bolt hole diameter, the second bolt hole diameter, and the third bolt hole diameter such that, in the installed configuration, there is a clearance between the set of bolts and the first set of bolt holes, and there is a clearance between the set of bolts and the second set of bolt holes, and there is a clearance between the set of bolts and the third set of bolt holes; and a frictional interface between the first rotor component (16, 30) and the second rotor component (16, 40); wherein the first set of bushings and a frictional interface between the first rotor component (16, 30) and the second rotor component (16, 40), are configured to bear more than 90% of a torque during rotation of the rotor assembly having the first and second rotor components (16, 30, 40) and wherein the set of bolts only transmits a portion of the torque between the first rotor component (16, 30) and the second rotor component (16, 40) in the event of over-torques exceeding the frictional forces of the frictional interface and the bushing elastic strength. a first rotor component (16, 30) having a first set of bushing receptacles and a first set of bolt holes arranged about a first rotational axis of the first rotor component (16, 30) wherein each bolt hole of the first set of bolt holes has a first bolt hole diameter;
