Abstract: A multiple natural frequency coupling apparatus (10) for connecting a rotatable driving member to a rotatable driven member of a drive line. The coupling apparatus (10) of the present invention provides a substantially cylindrical housing (12) having a longitudinal axis (13) with a substantially cylindrical outer shaft (34) coaxially aligned with and connected to the housing (12). A substantially cylindrical inner shaft (38) is coaxially aligned with the outer shaft (34) and the housing (12). A substantially cylindrical fluid chuck housing (26) is coaxially aligned with the housing (12), the outer shaft (34), and the inner shaft (38) wherein the fluid chuck housing (26) is connected to the inner shaft (38). A substantially cylindrical collapsible sleeve (50) is coaxially aligned with and between the fluid chuck housing (26) and the outer shaft (34), wherein the collapsible sleeve (50) may move between a non-actuated position, wherein the collapsible sleeve (50) does not engage the outer shaft (34) thereby providing the coupling apparatus (10) with a first torsional stiffness corresponding to a first natural frequency, and an actuated position, wherein the collapsible sleeve (50) engages the outer shaft (34) thereby providing the coupling apparatus (10) with a second torsional stiffness corresponding to a second natural frequency.
