         Parameters:
-            orders (Tuple[int, ...]): A $K$-tuple with the orders $M_k$ of each ring, for $k \in [0 : K)$. The sum $M_0 + M_1 + \cdots + M_{K-1}$ must be a power of $2$.
+            orders (tuple[int, ...]): A $K$-tuple with the orders $M_k$ of each ring, for $k \in [0 : K)$. The sum $M_0 + M_1 + \cdots + M_{K-1}$ must be a power of $2$.
 
-            amplitudes (Tuple[float, ...]): A $K$-tuple with the amplitudes $A_k$ of each ring, for $k \in [0 : K)$.
+            amplitudes (tuple[float, ...]): A $K$-tuple with the amplitudes $A_k$ of each ring, for $k \in [0 : K)$.
 
-            phase_offsets (Optional[Tuple[float, ...] | float]): A $K$-tuple with the phase offsets $\phi_k$ of each ring, for $k \in [0 : K)$. If specified as a single float $\phi$, then it is assumed that $\phi_k = \phi$ for all $k \in [0 : K)$. The default value is `0.0`.
+            phase_offsets (Optional[tuple[float, ...] | float]): A $K$-tuple with the phase offsets $\phi_k$ of each ring, for $k \in [0 : K)$. If specified as a single float $\phi$, then it is assumed that $\phi_k = \phi$ for all $k \in [0 : K)$. The default value is `0.0`.
 
             labeling (Optional[Array1D[int] | str]): The binary labeling of the modulation. Can be specified either as a 2D-array of integers (see [base class](/ref/Modulation) for details), or as a string. In the latter case, the string must be equal to `'natural'`. The default value is `'natural'`.

         Parameters:
