Abstract
An encoder is connected to an elevator traction machine shaft for sensing rotation of the machine shaft. The connector assembly includes a flexible torque-transmitting rod to minimize lateral deflection forces imparted to the encoder shaft by reason of misalignment between the machine and encoder shafts. A flexible collar is used to interconnect the flexible torque-transmitting rod with the encoder shaft.
