Abstract: A drive system comprising a rotatable input disc that receives an input rotational force and rotates about a longitudinal axis, where the input disc comprises driving features formed on its interior face. The drive system also comprises a rotatable output disc that rotates about the longitudinal axis and comprises driving features formed on its interior face, where the output disc provides an output rotational force. The drive system comprises a drive core between the interior face of the input disc and the interior face of the output disc to translate the input rotational force to the output rotational force. As the input disc is rotated by the input rotational force, engaging feature(s) of power disc(s) in the drive core engages the driving features of the input disc causing rotation of each power disc. As the power disc(s) is rotated, the engaging feature(s) of each power disc(s) engages the driving features of the output disc causing rotation of the output disc.
