Clamping desired torques

Hi, 
I am using joint_trajectory_controller for a kinova gen3 7 dof. 
Looking at this config file https://github.com/Kinovarobotics/ros2_kortex/blob/main/kortex_description/arms/gen3/7dof/urdf/kortex.ros2_control.xacro
we can use only "position" command interface.

Is the driver internally clamping the desired torques to avoid going over joint limits ?
Thank you in advance
