A propeller hub assembly comprises a driven member having an outer cylindrical housing and an inner cylindrical housing. The inner cylindrical housing is coaxially fixedly coupled and radially spaced from the outer cylindrical housing, and includes a plurality of radially inwardly directed circumferentially spaced ribs oriented parallel to an axis of the inner cylindrical housing. The propeller hub assembly further includes a driving member which comprises a cylindrical member having an axis of rotation. An opening passes through the driving member coaxial with the axis of rotation and is adapted for receiving a drive shaft. The driving member further includes a plurality of radially outwardly extending ribs oriented parallel to the axis of rotation and terminating radially at a diameter substantially equal to an inner diameter of the inner cylindrical housing. The outwardly extending ribs of the driving member intermesh with the inwardly extending ribs of the inner cylindrical housing when the driving member is inserted into the inner cylindrical housing. The propeller hub assembly also includes a plurality of resilient rod-shaped elements for inserting into the inner cylindrical housing with the driving member. At least one of the plurality of rod-shaped elements is positioned between each adjacent one of the ribs of the driving member and the inner cylindrical housing for absorbing shock loading during torque transfer between the driving member and the driven member.
