Original Abstract Submitted
A device for securing an attachment to a coupler. The device includes: a retention pin defining an elongate direction and configured to be disposed on the coupler, where, to secure the coupler to the attachment, the pin can move in the elongate direction to insert a first end, of the retention pin, into an opening in the attachment; and a thermoactuator including: a chamber associated with the coupler and containing a material that changes volume with temperature, where an end of the chamber is sealed with a piston that is mechanically connected to the retention pin proximate to a second end of the pin, the second end being disposed opposite the first end; and an electric temperature-altering device that, when activated, changes the temperature and volume of the material causing the piston to exert a force on the pin that moves the pin relative to the opening in the attachment.
