at least one dimple formed in each of said spaced lugs for reducing stress applied to said yoke and preventing said spaced lugs from bending as said yoke rotates around said longitudinal axis, each of said spaced lugs extends to a head and has a neck being wider in width than said head and sloping sides interconnecting said head with said neck for reinforcing said yoke as said yoke rotates around said longitudinal axis.
