### Question: **The following coupling allows small angular misalignments between two transmitting shafts:** #### Options: - None of the above - Universal coupling - Oldham coupling - Muff coupling --- ## **Correct Option** ### **Universal coupling** **Explanation:** A **Universal coupling** (also known as a universal joint or U-joint) is specifically designed to allow angular misalignment between two shafts. It is commonly used in automobile drive shafts and other machinery where shafts are not perfectly aligned. - **Oldham coupling** allows parallel misalignment. - **Muff coupling** does not allow for any misalignment. - **Universal coupling** allows angular misalignment. --- **Correct answer: Universal coupling**
