Abstract: A container closure node system includes a closure chassis coupling device that couples to a container closure for a container aperture. The closure chassis coupling device includes a first plate member that includes a first securing element and a second securing element. The closure chassis coupling device also includes a second plate member that includes a third securing element that is configured to couple to the first securing element and a fourth securing element that is configured to couple to the second securing element. At least one of the first plate member and the second plate member includes a container closure engagement member that is configured to engage the container closure to prevent rotational movement of the closure chassis coupling device relative to the container closure when the third securing element is coupled with the first securing element and the fourth securing element is coupled with the second securing element.
