Abstract: A golf club shaft is provided including a metal tip section and a composite butt section. The butt section includes a reduced diameter portion telescopically received within an axial bore of the tip section. An adhesive is disposed between the tip section and the butt section to secure the two together. An insulating layer may be disposed between the tip section and the butt section to prevent galvanic corrosion.

Abstract: A device-coupled golf club 80 includes a club head 64 which is assembled with a shaft 22 by use of a coupling device 40. Club head 64 is formed with a hosel 68 which is formed with a bore 70 having threads 76 formed in an upper portion thereof and a floor 74 at the base thereof. Coupling device 40 is formed with a body 41 having a bore 42 formed axially therethrough. A flange 44 is formed radially outwardly from one end of the body 41 and is formed with threads 50 from the flange toward the opposite axial end of the body. A ferrule 56 is located on shaft 22 and a tip end 30 of the shaft is inserted into bore 42 of body 41 and secured there by an epoxy glue 82. An exterior surface of body 41 is formed with threads 50 which engage threads 76 formed within bore 70 of hosel 68 to removably secure device 40 with head 64 whereby shaft 22 is assembled with the head 64 to form club 80.

Abstract: A golf club shaft including a damping layer which serves to reduce the amplitude of vibrational waves subject upon a golf club shaft is provided. The damping layer which includes, at least in part, an elastomeric material is coated to the inner diameter of the golf club shaft along a desired length. A method is also provided which relates to reducing the effects of induced modes of vibration upon a golf club shaft.
